Known Apple leaker Jon Prosser has claimed in a tweet that Apple will host its launch event on March 23. He has also speculated that the event may see the launch of the much-awaited AirTags. AirTags are coin-sized trackers which users can attach to any device that they fear losing, like car keys or a TV remote. Their location can then be tracked using Apple's Find My Device service, and they can be made to produce sound to make them easier to find. The rumoured event may also see the launch of updated iPad Pro models, along with updated AirPods and an updated Apple TV device.
